CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application is a national phase entry under 35 U.S.C. § 371 of International Application No. PCT / KR2015 / 011340 filed Oct. 26, 2015, which claims priority to Korean Application No. 10-2014-0147318 filed on Oct. 28, 2014, all of which are incorporated herein by reference.TECHNICAL FIELD

[0002] The present invention relates to a method for measuring the peeling stability of a release film and a release film laminate.BACKGROUND ART

[0003] A release film is a film which facilitates handling and transport of a product and can be easily separated, and has been utilized for various uses. For example, the release film may be used as a carrier film for an adhesive film. In this case, when a plurality of release films is used, there may occur a phenomenon in that an adhesive is lifted up or a problem in that an adhesive is transferred to the release film, depending on each difference in release strength. Therefore, there is a need for a veri...
